  Direct Catalytic Anti-Markovnikov Hydroetherification of Alkenols

  摘要：

  A direct intramolecular anti-Markovnikov hydroetherification reaction of alkenols is described. By employing Catalytic quantities of commercially available 9-mesityl-10-methylacridinium perchlorate and 2-phenyl-malononitrile as a redox-cycling source of a H-atom, we report the anti-Markovnikov hydroetherification of alkenes with complete regioselectivity, In addition, we present results demonstrating that this novel catalytic system can be applied to the anti-Markovnikov hydrolactonization of alkenoic acids.

  general, and functional group tolerant intramolecular hydroalkoxylation and hydroacyloxylation of unactivated olefins using a Co(salen) complex, an N-fluoropyridinium salt, and a disiloxane reagent is described. This reaction was carried out at room temperature and afforded five- and six-membered oxygen heterocyclic compounds, such as cyclic ethers and lactones. The Co complex was optimized for previously

  描述了使用 Co(salen) 配合物、N-氟吡啶鎓盐和二硅氧烷试剂对未活化烯烃进行温和、通用和官能团耐受的分子内加氢烷氧基化和加氢酰氧基化。该反应在室温下进行，得到五元和六元氧杂环化合物，如环醚和内酯。通过未活化烯烃的加氢官能​​化，Co 配合物针对先前稀有介质环的形成进行了优化。强大的 Co 催化剂体系还可以使 O-保护的链烯醇脱保护加氢烷氧基化和链烯基酯加氢酰氧基化，直接得到环醚和内酯。研究了脱保护的底物范围和机理证明。
